RE: Avoiding app server restarts while doing struts development
I am using Weblogic 6.1. I always deploy a developing web application as a DIRECTORY instead of WAR file. I found that I can deploy new java class by simply copy it into the right place of WEB-INF/classes directory (not to mention JSP files, it works for JSP too). But it doesn't work for resource bundle properties files. Weblogic 6.1 will auto-deploy the whole web application when it finds that there are some new class file in WEB-INF/classes. But after several times of auto-reploying processes, the server usually encounters some sort of out-of-memory problem. Then you have to restart Weblogic again. Regards, Vincent --- Marco Mistroni [EMAIL PROTECTED] HI, I guess those changes,which have 'context scope', need Always a redeploy Only changes that don't need a redeploy can be jsp changes (provided that You deploy your application as a 'directory' rather than war file) Regards marco -Original Message- From: Abhishek Srivastava [mailto:[EMAIL PROTECTED] Sent: 01 March 2004 11:28 To: 'Struts Users Mailing List' Subject: Avoiding app server restarts while doing struts development Hello All, I develop my apps on weblogic app server. When doing development on struts I feel for every little operation (change in resource file, change in source file, change config files) it requires me to either redeploy the app or to restart the app server. I have tried to switch to the debug mode, but still the number of redeploys or restarts have not reduced. I find these very time-consuming.

JSP context in an action
Does anyone know how to retrieve the servlet context of a given jsp and place an object in that context (say a map) and then request the page ? I've been putting together a email templating system using velocity, but logic tells me i can do this using the servlet and struts api's without using velocity. Velocity wont let me retrieve the *.vm file without extending velocity servlet which i dont see as nessesary other than to do this. I want to do something like this DynaActionForm theForm = (DynaActionForm) form; jspContext = ... Map map = BeanUtils.describe(theForm); jspContext.setAttribute(email,map); //and now request the page and stream it. .. ??? My nose is firmly lodged in the servlet and struts api's, just hoping someone can help nudge me in the right direction. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
ServletContextListener init parameters
Hi all,
I have my ActionServlet serving as a ServletContextListener:
public class ActionServlet

ServletContextListener
In the following method (which gets called upon startup) I need the
ActionServlet init Parameters:
public void contextInitialized(ServletContextEvent event)
I want to do something like:

ServletContext ctx = event.getServletContext();
Enumeration e = ctx.getInitParameterNames();
while (e.hasMoreElements()) {

}
}
Unfortunatly when I use the code above, my enumeration is empty.
My web.xml looks like this:

Struts logic combined with the struts validato
Hello,
I am making a registration procedure that works with some logic based on the
choices the customer makes on a previous page
logic:equal name=LogonForm property=customertype scope=session
value=business
span class=labellabelbean:message
key=text.data.label.bill_vat_number//label/span
html:text property=bill_vat_nr styleId=bill_vat_nr /
/logic:equal
Problem description :
When a customer is of customertype 'business' the field bill_vat_nr is
showed on the page and is required when a customer is not of customertype
'business' the field bill_vat_nr is not showed on the page and theirfor is
not required
I tried to use a standard struts validator implementation
field property=bill_vat_nr depends=required
arg0 key=text.data.label.bill_vat_number/
arg1 key=${dummy}/
/field
I first thought about using the requiredif implementation. Problem is that I
only get it to work with elements from the same form.
The result :
The bill_vat_nr is required even if it has been left out of the form by
struts logic
My question :
Is their a way to combine struts logic and the validator framework? Do I
have to write a custom validator that does some kind of introspection on the
jsp? Or are their validators that are used for that purpose? What would be
the best solution to tackle this problem?
Tnx in advance

Re: JSP context in an action
Mark,
I'd like to know how to do what you're but, unless someone else knows, how
about a different approach:
You could have a store tag which gets the body of a tag and stores it
somewhere (in the request or session or in a bean in the request or session)
and then forwards to an email action which then gets the stored content and
sends an email. Something like:
--EmailTemplate.jsp-
custom:store name=myForm property=emailContent scope=session
-- format your email here -
/custom:store
logic:forward name=emailForward/
--- StoreTag.java-
package lib.framework.taglib;
import javax.servlet.jsp.tagext.BodyTagSupport;
import javax.servlet.jsp.JspException;
import org.apache.struts.util.RequestUtils;
import org.apache.commons.beanutils.BeanUtils;
/**
* @author Niall Pemberton
* @version 1.0.0
*/
public class StoreTag extends BodyTagSupport {
protected String name = null;
protected String property = null;
protected String scope = null;
public StoreTag() {
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setProperty(String property) {
this.property = property;
}
public String getProperty() {
return property;
}
public void setScope(String scope) {
this.scope = scope;
}
public String getScope() {
return scope;
}
public int doAfterBody() throws JspException {
org.apache.struts.action.RequestProcessor ccc;
String value = null;
if (bodyContent != null) {
value = bodyContent.getString().trim();
}
if (property == null) {
pageContext.setAttribute(name, value, RequestUtils.getScope(scope));
} else {
// find the bean
Object bean = RequestUtils.lookup(pageContext, name, scope);
if (bean == null)
throw new JspException(Cannot find bean '+name+' in scope '+scope+');
try {
BeanUtils.setProperty(bean, property, value);
}
catch (Exception ex) {
throw new JspException(Error setting property '+property+' on bean

RE: DispatchAction and validate
Yes. The DispatchAction will only invoke the method defined in the request under the name defined in the parameter attribute of your action mapping. So if I had update() and restore() as methods in a DispatchAction, and I only wanted to validate on the update, then I would only define validate=true in the action mappping for the DispatchAction which is designated to invoke update(). This is assuming you have two separate action mappings which map to the same DispatchAction. robert -Original Message- From: Frers Michael [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 02, 2004 3:23 AM To: Struts Users Mailing List Subject: DispatchAction and validate Hello i want to use DispatchAction now my questions is can i use in one action the struts-config entry validate=true and in the other action validate=false Thx for any hints Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: ServletContextListener init parameters
The problem is your servlet init parameters don't exist in the ServletContext.
If you want them to be available to your code, then define them
as init parameters to your application:

RE: Send the response to a different frame
Hi, The one page you always want to reload can contain this tag: body onload=parent.navleft.location.href='navleft.jsp'; with which you fill the another frame(s).

Re: JSP context in an action
I'm still chewing on the problem. But a custom tag lib would seem a
possibility. I ended up using a velocity servlet and doing things that
way, my aim in trying otherwise was not to have to use velocity as its
another bunch of libraries that in theory I shouldn't need.
Ideally i'd have a template directory under WEB-INF where numb-nuts
dreamweaver types can edit email templates and i particularly like the
expression syntax which is like jsp2. So i was trying to think of a way
of using just that.
Velocity would be a really tidy way of doing things if the
VelocityEngine class had a getTemplate method that takes in a file
rather than just a string. At the moment I've a velocity servlet thats
really only there to get around this problem.
But as things are its not that bad i've have just preferred not having
to have a velocity servlet running just to find the where abouts of the
template.
Using jsp even better as everythings already there, just how to drill
to what i need. RequestDispatcher could be an option request the file
get its context and then stuff the map in there, but could be
tree-barking or/and smoking too much crack.

You could have a store tag which gets the body of a tag and stores it

and then forwards to an email action which then gets the stored

sends an email. Something like:

Subject: Struts logic combined with the struts validato
Hello,
I am making a registration procedure that works with some logic based on
the
choices the customer makes on a previous page
logic:equal name=LogonForm property=customertype scope=session
value=business
span class=labellabelbean:message
key=text.data.label.bill_vat_number//label/span
html:text property=bill_vat_nr styleId=bill_vat_nr /
/logic:equal
Problem description :
When a customer is of customertype 'business' the field bill_vat_nr is
showed on the page and is required when a customer is not of customertype
'business' the field bill_vat_nr is not showed on the page and theirfor is
not required
I tried to use a standard struts validator implementation
field property=bill_vat_nr depends=required
arg0 key=text.data.label.bill_vat_number/
arg1 key=${dummy}/
/field
I first thought about using the requiredif implementation. Problem is that
I
only get it to work with elements from the same form.
The result :
The bill_vat_nr is required even if it has been left out of the form by
struts logic
My question :
Is their a way to combine struts logic and the validator framework? Do I
have to write a custom validator that does some kind of introspection on
the
jsp? Or are their validators that are used for that purpose? What would be
the best solution to tackle this problem?

When I was fresh out of uni - back before the turn of the century, I interviewed for a position like that.

Best Error Page solution
Hi, What would be the best approach for handling the error messages? - set in very page %@ page errorPage=error_page.jsp %? - or to use a global mapping for handling error messages (eg. Session timeout, db connection broken, etc). Thanks for any hint. Julio
Re: JSP context in an action
Yeah, RequestDsiapatcher would work (like the struts IncludeAction) with the
StoreTag I sent, then you wouldn't have to forward in the jsp.
---Action.execute()---
// Determine Email Template
Strint emailTemplate = EmailTemplate.jsp;
// Get formatted email content
javax.servlet.RequestDispatcher rd =
servlet.getServletContext().getRequestDispatcher(emailTemplate);
rd.include(request, response);
String emailContent = form.getEmailContent();
// Process
send email---
--EmailTemplate.jsp-
custom:store name=myForm property=emailContent scope=session
-- format your email here -
/custom:store
...and use the StoreTag to just save the contents of the jsp in a
bean/request/session

P.S. The first line in the doAfterBody() was a mistake in the StoreTag.

Re: Struts logic combined with the struts validator
Alexander -
Usually when I have this situation I just put in an else (or a
logic:notEqual in your case) which prints out the form field as hidden with
some bogus data in it. That bogus data will be enough to make the
validation pass of course.
I had thought about doing the requiredifpresent or something like that, but

RE: Semi-OT: Saving state when using EJB Session Beans and Struts
Thanks for the reply! That is kind of what is going on already. The Action's act as the local Java class talked about in the Business Delegate Pattern that create and cache the Stateful Session Bean (a different one per Action). They (the Actions) then use the Session Bean's business logic. This is done in a standard way though where each Session Bean will implement an interface that is common to all of the other Session Beans in the application. This way each action simply calls a factory and based on the way the factory is called, a Stateful Session Bean for that type of action is returned, then cached in the Action. All actions then can make the submit(...), inspect(...), etc. calls common to all types of Session Beans (but performed differently by each one). The question is though, for these actions, shouldn't they keep session state that will match the Stateful Session Beans? Typically, I know you want have your Model hold Session state while your client holds request state, but in this case, where the Action needs to remember the cached Session Bean, doesn't it seem to make sense to mark the Action as session scope in the struts config file as well? -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Monday, March 01, 2004 5:35 PM To: Struts Users Mailing List Subject: Re: Semi-OT: Saving state when using EJB Session Beans and Struts On 03/01/2004 05:47 PM Smith, Darrin wrote: In short, the Actions will be calling various Stateful Session Beans to do the actual work.

Struts not suitable for shared hosting?
Hi everybody, I have come across this information on the net and I'm not sure if it's true. Basically they say that struts is known to hog server resources and that's why it shouldn't be used a shared tomcat instance like in ensim's webppliance. I'm now on the try to deploy a struts application on an ensim shared server (quite cheap) and I'm wondering if this is practical/feasible. Somebody knows if this is possible? I'm having a hard time to get done the things needed by this application by the sysadmins (*.do mapping, log permissions, ...), but I still haven't lost the hope. Private Tomcat/JVM allows you to run your own tomcat container within your own virtual process. You will have the flexibility to stop and start Tomcat, customize it and configure it to fit your needs. This will give you the capability to run struts and other frameworks known to hog server resources. http://www.displayhosting.net/services/javahosting.php Regards, Tomeu Vizoso - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

[REPOST] MockStrutsTestCase problem
Sorry for the repost, but I really am stuck on this. If anyone could help,
I'd appreciate it.
I'm having a problem setting up tests where errors are created during
validation by a DynaActionForm using MockStrutsTestCase. Here's my code:
The DynaActionForm:
===
package test;
import javax.servlet.http.*;
import org.apache.struts.action.*;
public class BogusForm extends org.apache.struts.action.DynaActionForm {
ActionErrors errors = new ActionErrors ();
public ActionErrors validate ( ActionMapping mapping,
HttpServletRequest request ) {
errors.add ( error, new ActionError ( error.message ) );
return errors;
}
}
The Action:
===
package test;
import javax.servlet.http.*;
import org.apache.struts.action.*;
/**
* @struts.action
*name=BogusForm
*input=.doActivity
*path=/Bogus
* @struts.action-forward
*name=doActivity
*path=.doActivity
*/
public class BogusAction extends org.apache.struts.action.Action {
public ActionForward execute ( ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response )
throws Exception {
return mapping.findForward ( doActivity );
}
}
The MockStrutsTestCase:
===
package test;
import javax.servlet.*;
import servletunit.struts.*;
public class TestBogusAction extends MockStrutsTestCase {
public void testFormPassed () {
setRequestPathInfo ( /Bogus );
actionPerform ();
verifyNoActionErrors ();
}
public void testFormFailed () {
setRequestPathInfo ( /Bogus );
actionPerform ();
verifyActionErrors( new String [] { error.message } );
}
}
The result:
===

Since the Form just creates an error, I should get exactly the opposite test
results from what I'm getting, right? It seems as though the
MockStrutsTestCase cannot see the errors generated by the DynaActionForm
even though the source says it should do exactly that. Any help appreciated.

Struts wizard workflows and stxx
Hi I am developing using struts and the stxx extensions that replace the use of beans and jsp's with XML and XSLT. I am working on a site where as users register it asks them for a lot of information.. So i want to split this over a few pages of forms.. page 1 will let them choose a username and password page 2 will let them enter their personal details (forename,surname,email etc) page 3 will let them enter their postal address then i want my Action to pool all the details and create their account and forward them to another page. Now the question is what is the best way to go about this? I have found the following on the jakarta website : == How can I create a wizard workflow? The basic idea is a series of actions with next, back, cancel and finish actions with a common bean. Using a LookupDispatchAction is reccomended as it fits the design pattern well and can be internationalized easily. Since the bean is shared, each choice made will add data to the wizards base of information. A sample of struts-config.xml follows: form-beans form-bean name=MyWizard type=forms.MyWizard / /form-beans !-- the first screen of the wizard (next action only available) -- !-- no validation, since the finish action is not available -- actions action path=/mywizard1 type=actions.MyWizard name=MyWizard validate=false input=/WEB-INF/jsp/mywizard1.jsp forward name=next path=/WEB-INF/jsp/mywizard2.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action !-- the second screen of the wizard (back, next and finish) -- !-- since finish action is available, bean should validated, note validation should not necessarily validate if back action requested, you might delay validation or do conditional validation -- action path=/mywizard2 type=actions.MyWizard name=MyWizard validate=true input=/WEB-INF/jsp/mywizard2.jsp forward name=back path=/WEB-INF/jsp/mywizard1.jsp / forward name=next path=/WEB-INF/jsp/mywizard3.jsp / forward name=finish path=/WEB-INF/jsp/mywizarddone.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action !-- the last screen of the wizard (back, finish and cancel only) -- action path=/mywizard3 type=actions.MyWizard name=MyWizard validate=true input=/WEB-INF/jsp/mywizard3.jsp forward name=back path=/WEB-INF/jsp/mywizard2.jsp / forward name=finish path=/WEB-INF/jsp/mywizarddone.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action The pieces of the wizard are as follows: forms.MyWizard.java - the form bean holding the information required actions.MyWizard.java - the actions of the wizard, note the use of LookupDispatchAction allows for one action class with several methods. All the real work will be done in the 'finish' method. mywizard[x].jsp - the data collection jsp's mywizarddone.jsp - the 'success' page mywizardcancel.jsp - the 'cancel' page Is it possible to do this when using stxx? and what would be the setup of my struts-config.xml document for this? Does anyone have any example code that acheives something similar to what i am looking for?

Re: calculating sum inside logic:iterate
Depends how you've done things. If your items are nested in a form (indexed/mapped proerties) you could have a total that is calculated there. Thus no need to do it in an action or a jsp.

Good point about the testing. I didn't mention it because I was responding to specific issues in the original email, but testing is everything. Your end-user/customer will not care if you used all the trendy GoF patterns, if the software doesn't work. The software must work. Testing is the best way that we have at this time of ensuring that.

Re: calculating sum inside logic:iterate
Technically this seems to be a business method, logic that would be better handled in your model code. So for example you have a ShoppingCart class which has a getItems() method to get your collection of items and a getTotal() method to add their prices. Not the answer you're looking for I think but my 2 cents. Nick Marco Mistroni wrote: Hi all, I have a colletion of items that have a method called price.

RE: Struts wizard workflows and stxx
Hi , What you are looking for may be fits in workflow pattern. We had some discussion about this on the list some time back. the approach you have seen will work well, but the only problem that I can see is the form will stay in session. And being a web application, the user can jump any where.And hence no way to clearly define the end point for workflow or force user to follow the exact page flow. So first decide what is your exact requirements it just one off requirement or you may need to share data across pages in many places.And mainly, putting form bean in session is tolerable for your web application(volume of traffic you are expecting etc .) IF you need an out of box solution for those things, have a look at the following extension. http://www.livinglogic.de/Struts/index.html I am porting the project to source forge and planning a new version as well.But the current version is stable and supports all work flow requirements. If you have any doubts, I can help you with the same. HTH. Regards, Shirish -Original Message- From: Edd Dawson [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 02, 2004 5:26 PM To: [EMAIL PROTECTED] Subject: Struts wizard workflows and stxx Hi I am developing using struts and the stxx extensions that replace the use of beans and jsp's with XML and XSLT. I am working on a site where as users register it asks them for a lot of information.. So i want to split this over a few pages of forms.. page 1 will let them choose a username and password page 2 will let them enter their personal details (forename,surname,email etc) page 3 will let them enter their postal address then i want my Action to pool all the details and create their account and forward them to another page. Now the question is what is the best way to go about this? I have found the following on the jakarta website : == How can I create a wizard workflow? The basic idea is a series of actions with next, back, cancel and finish actions with a common bean. Using a LookupDispatchAction is reccomended as it fits the design pattern well and can be internationalized easily. Since the bean is shared, each choice made will add data to the wizards base of information. A sample of struts-config.xml follows: form-beans form-bean name=MyWizard type=forms.MyWizard / /form-beans !-- the first screen of the wizard (next action only available) -- !-- no validation, since the finish action is not available -- actions action path=/mywizard1 type=actions.MyWizard name=MyWizard validate=false input=/WEB-INF/jsp/mywizard1.jsp forward name=next path=/WEB-INF/jsp/mywizard2.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action !-- the second screen of the wizard (back, next and finish) -- !-- since finish action is available, bean should validated, note validation should not necessarily validate if back action requested, you might delay validation or do conditional validation -- action path=/mywizard2 type=actions.MyWizard name=MyWizard validate=true input=/WEB-INF/jsp/mywizard2.jsp forward name=back path=/WEB-INF/jsp/mywizard1.jsp / forward name=next path=/WEB-INF/jsp/mywizard3.jsp / forward name=finish path=/WEB-INF/jsp/mywizarddone.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action !-- the last screen of the wizard (back, finish and cancel only) -- action path=/mywizard3 type=actions.MyWizard name=MyWizard validate=true input=/WEB-INF/jsp/mywizard3.jsp forward name=back path=/WEB-INF/jsp/mywizard2.jsp / forward name=finish path=/WEB-INF/jsp/mywizarddone.jsp / forward name=cancel path=/WEB-INF/jsp/mywizardcancel.jsp / /action The pieces of the wizard are as follows: forms.MyWizard.java - the form bean holding the information required actions.MyWizard.java - the actions of the wizard, note the use of LookupDispatchAction allows for one action class with several methods. All the real work will be done in the 'finish' method. mywizard[x].jsp - the data collection jsp's
Re: calculating sum inside logic:iterate
I see what you're saying. But at the same time, if you wanted to develop a shopping cart that you could plug onto any model. Then IMO calculating in a web tier bean say an action form isn't the most evil thing in the world. I agree entirely that the total should be calculated in the model, before say saving to the db. But I think there's a case for doing this in the web-tier.

Re: ServletContextListener init parameters
You can also do it with struts tags - expose the ServletContext as a
variable:
bean:page id=servletContext property=application/
...and get an enumeration of init parameter names
logic:iterate id=contextParamName name=servletContext
property=initParameterNames
Init Parameter Name: bean:write name=contextParamName/
/logic:iterate
...but theres nothing in strust to access getInitPramater(name) for the
value. So it would have to be scriptlet:
Init Parameter Value: %=
servletContext.getInitParameter(contextParamName.toString()) %

The problem is your servlet init parameters don't exist in the

If you want them to be available to your code, then define them
as init parameters to your application:

Hi all,
I have my ActionServlet serving as a ServletContextListener:
public class ActionServlet
extends org.apache.struts.action.ActionServlet implements
ServletContextListener
In the following method (which gets called upon startup) I need the
ActionServlet init Parameters:
public void contextInitialized(ServletContextEvent event)
I want to do something like:
public void contextInitialized(ServletContextEvent event) {
ServletContext ctx = event.getServletContext();
Enumeration e = ctx.getInitParameterNames();
while (e.hasMoreElements()) {
log.debug(Parameter: + e.nextElement());
}
}
Unfortunatly when I use the code above, my enumeration is empty.
My web.xml looks like this:

Re: [REPOST] MockStrutsTestCase problem

Thanks for the pointer to DynaValidatorForm. I can see how that would be

However, I tried making the change you suggest and I get the same result.
Any other advice? It's as if the ActionErrors generated by the form are

Struts Workflow - Questions ?
Hi, I'm trying to resolve a problem I have by making use of Struts Workflow - Using this as I need something that will prevent jump-out within the process The login process of my app has a number of conditions which dictate which page I send the user to next. I understand the basic's of the Struts Workflow but am a little confused when we get to the looping/forwarding aspects Basically the section of the flow is as follows: SecurityFilterAuthentication - Is User Authenticated ? If Y - StartWorkflow - Retrieve User Settings - Is 3fromN login required ? If Y - Do 3FromN Else -Record Successful Login - ...Continue Workflow The 3FromN section has to allow the user 3 attempts and then do a Lock Out Action or if successful continue to the Record Successful Login Action How do I make those decisions within the workflow ? Do I have to have an action for every decision node or can I set what the next action should be in the active one using return (new ActionForward(nextAction)); Regards Joanne Corless - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Since the Form just creates an error, I should get
exactly the opposite test
results from what I'm getting, right? It seems as
though the
MockStrutsTestCase cannot see the errors generated
by the DynaActionForm
even though the source says it should do exactly
that. Any help appreciated.

RE: DispatchAction and validate
do I need an updated .xdt file for this? y xdoclet generated Struts-config.xml is not having the action mappings for the actiin class of mine, extending Dispatch Action.

The DispatchAction will only invoke the method defined in the request under the name defined in the parameter attribute of your action mapping.

Use request.getAttribute(id). hth, Shyam Let me elaborate my question #3: If my .JSP has a html:form action=/app/UpdateOrder?id=30 , I know when I click a 'submit' button to get to an Action class, I can retrieve the id in my Action class by doing String id = Request.getParameter(id); But if my .jsp uses a link to pass the id such as a href=app/UpdateOrder.exec?id=30..

Re: Semi-OT: Saving state when using EJB Session Beans and Struts
It's difficult to know what scenario you are talking about here. I assume you mean to cache the EJBs in the user's servlet session, so you will have several remote EJBs in there depending on how many different actions the user has accessed. It sounds like you need to do this to allow transaction management across a group of data operations? I would not do it by caching the EJBs at all, or having stateful session beans. I would keep my actionformbean in the user's servlet session instead, accumulating the data over several http requests and then marshall the whole collection of data across to the EJB session in one. Struts is good at that. I expect you'd give yourself more headaches than it's worth, trying to collect the user's session data in the EJB layer. It sounds like you are writing a web interface for an already existing client-server app. On 03/02/2004 03:42 PM Smith, Darrin wrote: Thanks for the reply! That is kind of what is going on already.

Should Action or ActionForm be accessing business delegates?
The reading I've done suggested that one of the Action class's primary responsibilities was to access the business layer. Then today I was looking at the core j2ee patterns and it showed the View Helper accessing the business layer. I associated (maybe mistakenly) the View Helper pattern with the ActionForm and was then wondering if I should design our ActionForm's to have direct access to the business layer. Thoughts? Thanks, Brian Barnett
Re: Date attribute in ActionForm
Bean utils (what struts uses in this case) sucks when it comes to parsing anything but Strings. Generally what I do is make put String getter/setter methods on the Form, then in those (or in the Action) use a SimpleDateFormat to parse the string into a date. One other thing to note there is that the date format MM/dd/yy will parse 1/1/04 as 01/01/2004, but 1/1/4 as 01/01/0004, so you need to handle that yourself. Same trick with numeric classes.

RE: Should Action or ActionForm be accessing business delegates?
I'd say no. Don't have the ActionForm (just a JavaBean with some validation in it...maybe) access the business layer. To me, the Action acts as the local Java class talked about in the Business Delegate Pattern that creates and caches a Stateful Session Bean. Use them (the actions) or add a true form of the Business Delegate Pattern maybe. Of course, this is just my opinion...don't recall reading that it should be done this way for every case. -Original Message- From: Barnett, Brian W.

pure Struts implementation of form with an html:checkbox that enables/disables an html:text ?
Hi all,
Is there a better way to use a checkbox to dynamically disable/enable a text box,
within a form?
I want the end user to be unable to fill out the text field until after she has
checked the check box.
I would prefer not to use javascript. Is there a pure Struts way to do this?
My searches have come up with some vaguely related material, but nothing that provides
a javascript-free solution.
the jsp:
...
body
script
function GrayOut(obj_checkbox)
{
if(obj_checkbox.checked)
{
obj_checkbox.form.boundIP.disabled = false;
}
else
{
obj_checkbox.form.boundIP.disabled = true;
}
}
/script
...
html:form action=/NewIPRecordSubmit focus=baseIP
...
IP Address
...
html:text property=baseIP styleClass=textbox style=size:114/
...
html:checkbox property=ipRangeEnabled value=no onclick=GrayOut(this)/

RE: Semi-OT: Saving state when using EJB Session Beans and Struts
Currently the design is to cache the instances of the Stateful Session beans, and do that in the Actions themselves. One SSB per Action. The reason for the SSB is primarily for the transaction support (online ordering) but also because addition EJB use will be needed in the future anyway (interfacing with an existing system that will eventually use Message Driven Beans to communicate...using simply JDBC to populate a posting table now). You are correct in that the web interface is for an existing application (the one that will eventually talk through a message queue...but today only works with posting tables...another reason why transaction support is a good thing). I guess it might make sense to keep the intermediate information (the lists that can be ordered, the patients the items can be order for, etc.) in the servlet's session as you say. The SSB's though would still be used though to get the intermediate data to be passed back and held in the servlet. Example...the user needs to get a list of patients that the order will be applied to. The RetrievePatientsAction gets invoked, and it in turn creates a SSB (if one isn't already cached) to perform the actual business logic needed to do this step. Using that data, a JSP is created and the user selects a patient, and then requests a list of items applicable to that patient. Then the request to retrieve that information is passed in and a similar process occurs to the one above. Finally, all of the information is available, and an order is place that goes through a similar process. This is a semi-contrived example of course but it is an example of what the thinking is. -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 02, 2004 12:21 PM To: Struts Users Mailing List Subject: Re: Semi-OT: Saving state when using EJB Session Beans and Struts It's difficult to know what scenario you are talking about here.

Some cookie spec says: The path attribute is used to specify the subset of URLs in a domain for which the cookie is valid.

RE: Showing selected in struts option tag
Wendy,
Sounds good.
So updateAccounts() is in the jsp..I have similar functionality to update the backend
struts classes on changing the value in this drop downm, especially wondering how to
tie in struts with javascript becuase i want to do something like the following in my
javascript function:
SCRIPT LANGUAGE=JavaScript
function onChange(){
//call another struts class - window.location.href=booksDsiplay.do or something like
that
}
/script
can we invoke struts mapings and navigation from javascript.
also i got following error using htmlOptions, though I have the getter for the BEAN
property supervisor.wondering why. Thanks in advance.
javax.servlet.jsp.JspException: No getter method for property supervisors of bean

Thanks for the prompt reply.Had a quick question.
where do we mention this method? in the form's action class?
updateAccounts();
It's in the 'onchange' attribute of . The docs are here:
http://jakarta.apache.org/struts/userGuide/struts-html.html#select
Specifically:
onchange - JavaScript event handler executed when this element loses
input focus and its value has changed. [RT Expr]

RE: Showing selected in struts option tag
From: as as [mailto:[EMAIL PROTECTED] can we invoke struts mapings and navigation from javascript. Sure. The Struts tags have attributes for all the JavaScript handlers-- onclick, onblur, etc. Just keep it clear in your mind that in the simplest case, Struts code executes on the server, then HTML is delivered to the client, at which point the JavaScript runs. So you can't call a method in your Action class directly from JavaScript*, instead you'd have to cause another request to the server, usually by submitting the form. [*Actually I think something like this _is_ possible, but not with the basic JavaScript knowledge I have! Anyone care to toss out some search terms?

Thanks in advance. javax.servlet.jsp.JspException: No getter method for property supervisors of bean org.apache.struts.taglib.html.BEAN You will need to study the documentation for the html:options tag. It has many attributes, and they do different things when used in various combinations. For a start, post the section of JSP that's supposed to render this select tag, and tell us about 'supervisors'. Is it in the ActionForm? What type of Collection is it? What's happening is that Struts is calling the getSupervisors() method on some bean, and it's not the one that has that method. How you fix that depends on where 'supervisors' lives. -- Wendy Smoak Application Systems Analyst, Sr. ASU IA Information Resources Management - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Date attribute in ActionForm
Its also usually the case with dates that downs make less work for the user.

BODY onLoad Workaround
Hey everyone - So I have a Struts/Tiles page that I need to have a Javascript function called on when the page loads. Normally this is of course accomplished with the BODY onLoad event however this event isn't fired when my page loads and from doing extensive Googling I've found that this has something to do with the nature of Struts/Tiles pages (though I'm not sure what). What is the best workaround for this? Thanks so much, Alan
Re: Tiles problem
all the puts should be have
type=string
type=definition
type=page
depending on what it is.
For example if .portfolioLayout is a definition
put name=content value=.portfolioLayout type=definition /
if its a layout then it should be in the definition tag as the
content of the path attribute. The naming convention for layouts
usually refers to those files that are layouts not definitions as such.
definition name=main.base path=/layouts/mainLayout.jsp
...
I've used some of your names but i doubt they are that relevent to you.
definition name=activity.detail extends=main.base
put name=title value=Mellow World!!! type=string /
put name=content value=portfolio.default type=definition /
put name=app-specific value=/tiles/activityInfo.jsp type=page /
/definition
When did all this .somename business start then, i've seen this else
where. Looks like dirty php to me :o)

html:link problem
Hi list,
Just wondering if anyone has any bright ideas. Things that you can do
easily with an a ... tag, are not (easily) acheivable with a html:link.
For instance in the following code:
nested:iterate id=title name=%= Constants.TITLES_COLLECTION %
scope=request indexId=counter
html:link page=/findtitles.do
onmouseover=MM_swapImage('details%= counter %,...)...
/nested:iterate
counter will not resolve, although it will if the tag is an ordinary anchor.
Does anyone know a way around this? I have been resorting to using ordinary
a... tags but have just realised that there is no session control if
cookies are disabled. I have to use html:link...
thanks, al
Multiple Forms
I am working on a web project in which there is a need to submit two forms from a same html file. Does anybody have such experience as submitting two forms separately? Thanks!
Re: BODY onLoad Workaround
Iframe would be one possible hack. Have the page that loads run a
javascript function that drills back up to your page.
or an onload on an image, or simply execute the function in the page.
lastly have something like this in your layout
tile:get name=javascriptHack scope=page /
script language=javascript type=text/javascript
!--
function myfuction() {
c:out value=${javascriptHack} /;
}
//--
/script
body onload=myfuction()
Stick your method as a put in that tile and have it empty for those
page where not required.
put name=javascriptHack value=alert('my javascript hack')
type=string /
the rest of the time
put name=javascriptHack value= type=string /
So the function always runs just usually contains nothing.

Re: Semi-OT: Saving state when using EJB Session Beans and Struts
OK, go for it then. I think the only thing to be really concerned about is memory availability. If you're storing stuff in the user's session and maintaining SSBs, memory usage might build up quickly. Plus, depending on how critical your application is, you might have to worry about failure wiping out your SSBs before they're done. If you had stateless SBs, it wouldn't be a problem with fail-over support and a web farm :) On 03/02/2004 08:58 PM Smith, Darrin wrote: Currently the design is to cache the instances of the Stateful Session beans, and do that in the Actions themselves. One SSB per Action. The reason for the SSB is primarily for the transaction support (online ordering) but also because addition EJB use will be needed in the future anyway (interfacing with an existing system that will eventually use Message Driven Beans to communicate...using simply JDBC to populate a posting table now). You are correct in that the web interface is for an existing application (the one that will eventually talk through a message queue...but today only works with posting tables...another reason why transaction support is a good thing). I guess it might make sense to keep the intermediate information (the lists that can be ordered, the patients the items can be order for, etc.) in the servlet's session as you say. The SSB's though would still be used though to get the intermediate data to be passed back and held in the servlet. Example...the user needs to get a list of patients that the order will be applied to. The RetrievePatientsAction gets invoked, and it in turn creates a SSB (if one isn't already cached) to perform the actual business logic needed to do this step. Using that data, a JSP is created and the user selects a patient, and then requests a list of items applicable to that patient. Then the request to retrieve that information is passed in and a similar process occurs to the one above. Finally, all of the information is available, and an order is place that goes through a similar process. This is a semi-contrived example of course but it is an example of what the thinking is. -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 02, 2004 12:21 PM To: Struts Users Mailing List Subject: Re: Semi-OT: Saving state when using EJB Session Beans and Struts It's difficult to know what scenario you are talking about here. I assume you mean to cache the EJBs in the user's servlet session, so you will have several remote EJBs in there depending on how many different actions the user has accessed. It sounds like you need to do this to allow transaction management across a group of data operations? I would not do it by caching the EJBs at all, or having stateful session beans. I would keep my actionformbean in the user's servlet session instead, accumulating the data over several http requests and then marshall the whole collection of data across to the EJB session in one. Struts is good at that. I expect you'd give yourself more headaches than it's worth, trying to collect the user's session data in the EJB layer.

The Action's act as the local Java class talked about in the Business Delegate Pattern that create and cache the Stateful Session Bean (a different one per Action). They (the Actions) then use the Session Bean's business logic. This is done in a standard way though where each Session Bean will implement an interface that is common to all of the other Session Beans in the application. This way each action simply calls a factory and based on the way the factory is called, a Stateful Session Bean for that type of action is returned, then cached in the Action. All actions then can make the submit(...), inspect(...), etc. calls common to all types of Session Beans (but performed differently by each one). The question is though, for these actions, shouldn't they keep session state that will match the Stateful Session Beans? Typically, I know you want have your Model hold Session state while your client holds request state, but in this case, where the Action needs to remember the cached Session Bean, doesn't it seem to make sense to mark the Action as session scope in the struts config file as well? -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Monday, March 01, 2004 5:35 PM To: Struts Users Mailing List Subject: Re: Semi-OT: Saving state when using EJB Session Beans and Struts On 03/01/2004 05:47 PM Smith, Darrin wrote: In short, the Actions will be calling various Stateful Session Beans to do the actual work.

RE: BODY onLoad Workaround
Thanks Mark for your response.
The issue is that even without my layout, which contains the body tag,
if I add an onLoad event it is not fired.
I have already tried calling the javascript function from somewhere in
the page however it is always called before the entire page is actually
rendered, which means that certain items on the page that the function
operates on do not have all of their properties.
Is there no way to mimic a body onLoad completely?
